2. Description of the Related Art

Xanthan gum is a polysaccharide derived from the bacterial coat ofXanthomonas campestris. It is produced by the fermentation of glucose,sucrose, or lactose by the Xanthomonas campestris bacterium. After afermentation period, the polysaccharide is precipitated from a growthmedium with isopropyl alcohol, dried, and ground into a fine powder.Later, it is added to a liquid medium to form the gum.

Xanthan gum is a natural polysaccharide consisting of different sugarswhich are connected by several different bonds, such asβ-D-mannosyl-β-D-1,4-glucuronosyl bonds andβ-D-glucosyl-β-D-1,4-glucosyl bonds. Xanthan gum is at least partlysoluble in water and forms highly viscous solutions or gels.

Complete enzymatic degradation of xanthan gum requires several enzymaticactivities including xanthan lyase activity and endo-β-1,4-glucanaseactivity. Xanthan lyases are enzymes that cleave theβ-D-mannosyl-β-D-1,4-glucuronosyl bond of xanthan and have beendescribed in the literature. Xanthan degrading enzymes are known in theart e.g. have two xanthan lyases been isolated from Paenibacillusalginolyticus XL-1 (e.g. Ruijssenaars et al. (1999) ‘A pyruvatedmannose-specific xanthan lyase involved in xanthan degradation byPaenibacillus alginolyticus XL-1’, Appl. Environ. Microbiol. 65(6):2446-2452, and Ruijssenaars et al. (2000), ‘A novel gene encodingxanthan lyase of Paenibacillus alginolyticus strain XL-1’, Appl.Environ. Microbiol. 66(9): 3945-3950).

Glycoside hydrolases are enzymes that catalyse the hydrolysis of theglycosyl bond to release smaller sugars. There are over 100 classes ofglycoside hydrolases which have been classified, see Henrissat et al.(1991) ‘A classification of glycosyl hydrolases based on amino-acidsequence similarities’, J. Biochem. 280: 309-316 and the Uniprot websiteat www.cazy.org. The glycoside hydrolase family 9 (GH9) consists of over70 different enzymes that are mostly endoglucanases (EC 3.2.1.4),cellobiohydrolases (EC 3.2.1.91), β-glucosidases (EC 3.2.1.21) andexo-β-glucosaminidase (EC 3.2.1.165). A GH9 from Microbacteriumtestaceum StLB037 having 84.5% sequence identity to SEQ ID NO: 12, 79.1%sequence identity to SEQ ID NO: 10 and 74.0% sequence identity to SEQ IDNO: 14 has been published by T. Morohoshi et al, (2011) J. Bacteriol.193(8), 2072-2073.

In recent years xanthan gum has been use as an ingredient in manyconsumer products including foods (e.g. as thickening agent in salatdressings and dairy products) and cosmetics (e.g. as stabilizer andthickener in toothpaste and make-up to prevent ingredients fromseparating) and cosmetics (such as sun creams). Further xanthan gum hasfound use in the oil industry as well as an additive to regulate theviscosity of drilling fluids etc. The widespread use of xanthan gum hasled to a desire to degrade solutions or gels of xanthan gum therebyallowing easier removal of the byproducts. It has been suggested to adda xanthan lyase to a detergent composition in order to remove xanthangum containing stains, e.g. in EP0896998A, but this publication does notcontain any experimental data demonstrating any effect thereof.

The invention provides new and improved enzymes for the degradation ofxanthan gum and the use of such enzymes for cleaning purposes, such asthe removal of xanthan gum stains, and in the drilling and oilindustries.

SHORT DESCRIPTION OF THE FIGURE

FIG. 1 shows a plasmid map of the linear vector with gene insert for SEQID NO: 87.

DEFINITIONS

Allelic variant: The term “allelic variant” means any of two or morealternative forms of a gene occupying the same chromosomal locus.Allelic variation arises naturally through mutation, and may result inpolymorphism within populations. Gene mutations can be silent (no changein the encoded polypeptide) or may encode polypeptides having alteredamino acid sequences. An allelic variant of a polypeptide is apolypeptide encoded by an allelic variant of a gene.

Catalytic domain: The term “catalytic domain” means the region of anenzyme containing the catalytic machinery of the enzyme.

cDNA: The term “cDNA” means a DNA molecule that can be prepared byreverse transcription from a mature, spliced, mRNA molecule obtainedfrom a eukaryotic or prokaryotic cell. cDNA lacks intron sequences thatmay be present in the corresponding genomic DNA. The initial, primaryRNA transcript is a precursor to mRNA that is processed through a seriesof steps, including splicing, before appearing as mature spliced mRNA.

Cleaning or Detergent Application: the term “cleaning or detergentapplication” means applying the endoglucanase of the application in anycomposition for the purpose of cleaning or washing, by hand, machine orautomated, a hard surface or a textile.

Cleaning or Detergent Composition: the term “cleaning or detergentcomposition” refers to compositions that find use in the removal ofundesired compounds from items to be cleaned, such as textiles, dishes,and hard surfaces. The terms encompass any materials/compounds selectedfor the particular type of cleaning composition desired and the form ofthe product (e.g., liquid, gel, powder, granulate, paste, or spraycompositions) and includes, but is not limited to, detergentcompositions (e.g., liquid and/or solid laundry detergents and finefabric detergents; hard surface cleaning formulations, such as forglass, wood, ceramic and metal counter tops and windows; carpetcleaners; oven cleaners; fabric fresheners; fabric softeners; andtextile and laundry pre-spotters, as well as dish wash detergents). Inaddition to the endoglucanase, the detergent formulation may contain oneor more additional enzymes (such as proteases, amylases, lipases,cutinases, cellulases, endoglucanases, xyloglucanases, pectinases,pectin lyases, xanthanases, peroxidaes, haloperoxygenases, catalases andmannanases, or any mixture thereof), and/or components such assurfactants, builders, chelators or chelating agents, bleach system orbleach components, polymers, fabric conditioners, foam boosters, sudssuppressors, dyes, perfume, tannish inhibitors, optical brighteners,bactericides, fungicides, soil suspending agents, anti corrosion agents,enzyme inhibitors or stabilizers, enzyme activators, transferase(s),hydrolytic enzymes, oxido reductases, bluing agents and fluorescentdyes, antioxidants, and solubilizers.

Coding sequence: The term “coding sequence” means a polynucleotide,which directly specifies the amino acid sequence of a polypeptide. Theboundaries of the coding sequence are generally determined by an openreading frame, which begins with a start codon such as ATG, GTG, or TTGand ends with a stop codon such as TAA, TAG, or TGA. The coding sequencemay be a genomic DNA, cDNA, synthetic DNA, or a combination thereof.

Colour clarification: During washing and wearing loose or broken fiberscan accumulate on the surface of the fabrics. One consequence can bethat the colours of the fabric appear less bright or less intensebecause of the surface contaminations. Removal of the loose or brokenfibers from the textile will partly restore the original colours andlooks of the textile. By the term “colour clarification”, as usedherein, is meant the partial restoration of the initial colours oftextile.

Control sequences: The term “control sequences” means nucleic acidsequences necessary for expression of a polynucleotide encoding a maturepolypeptide of the present invention.

Such control sequences include, but are notlimited to, a leader, polyadenylation sequence, propeptide sequence,promoter, signal peptide sequence, and transcription terminator. At aminimum, the control sequences include a promoter, and transcriptionaland translational stop signals. The control sequences may be providedwith linkers for the purpose of introducing specific restriction sitesfacilitating ligation of the control sequences with the coding region ofthe polynucleotide encoding a polypeptide.

Degrading xanthan gum: The term “degrading xanthan gum” is definedherein as the depolymerization, degradation or breaking down of xanthangum into smaller components. The degradation of xanthan gum can eitherbe the removal of one or more side chain saccharides, the cutting of thebackbone of xanthan gum into smaller components or the removal of one ormore side chain saccharides and the cutting of the backbone of xanthangum into smaller components. The degradation of xanthan gum canpreferably be measured using the viscosity reduction method as describedin example 6.

Examples of conservative substitutions are within the groups of basicamino acids (arginine, lysine and histidine), acidic amino acids(glutamic acid and aspartic acid), polar amino acids (glutamine andasparagine), hydrophobic amino acids (leucine, isoleucine and valine),aromatic amino acids (phenylalanine, tryptophan and tyrosine), and smallamino acids (glycine, alanine, serine, threonine and methionine). Aminoacid substitutions that do not generally alter specific activity areknown in the art and are described, for example, by H. Neurath and R. L.Hill, 1979, In, The Proteins, Academic Press, New York. Commonsubstitutions are Ala/Ser, Val/Ile, Asp/Glu, Thr/Ser, Ala/Gly, Ala/Thr,Ser/Asn, Ala/Val, Ser/Gly, Tyr/Phe, Ala/Pro, Lys/Arg, Asp/Asn, Leu/Ile,Leu/Val, Ala/Glu, and Asp/Gly.

Alternatively, the amino acid changes are of such a nature that thephysico-chemical properties of the polypeptides are altered. Forexample, amino acid changes may improve the thermal stability of thepolypeptide, alter the substrate specificity, change the pH optimum, andthe like.

Essential amino acids in a polypeptide can be identified according toprocedures known in the art, such as site-directed mutagenesis oralanine-scanning mutagenesis (Cunningham and Wells, 1989, Science 244:1081-1085). In the latter technique, single alanine mutations areintroduced at every residue in the molecule, and the resultant mutantmolecules are tested for cellulase and/or xanthan lyase activity toidentify amino acid residues that are critical to the activity of themolecule. See also, Hilton et al., 1996, J. Biol. Chem. 271: 4699-4708.The active site of the enzyme or other biological interaction can alsobe determined by physical analysis of structure, as determined by suchtechniques as nuclear magnetic resonance, crystallography, electrondiffraction, or photoaffinity labelling, in conjunction with mutation ofputative contact site amino acids. See, for example, de Vos et al.,1992, Science 255: 306-312; Smith et al., 1992, J. Mol. Biol. 224:899-904; Wlodaver et al., 1992, FEBS Lett. 309: 59-64. The identity ofessential amino acids can also be inferred from an alignment with arelated polypeptide.

Single or multiple amino acid substitutions, deletions, and/orinsertions can be made and tested using known methods of mutagenesis,recombination, and/or shuffling, followed by a relevant screeningprocedure, such as those disclosed by Reidhaar-Olson and Sauer, 1988,Science 241: 53-57; Bowie and Sauer, 1989, Proc. Natl. Acad. Sci. USA86: 2152-2156; WO 95/17413; or WO 95/22625. Other methods that can beused include error-prone PCR, phage display (e.g., Lowman et al., 1991,Biochemistry 30: 10832-10837; U.S. Pat. No. 5,223,409; WO 92/06204), andregion-directed mutagenesis (Derbyshire et al., 1986, Gene 46: 145; Neret al., 1988, DNA 7: 127).

Mutagenesis/shuffling methods can be combined with high-throughput,automated screening methods to detect activity of cloned, mutagenizedpolypeptides expressed by host cells (Ness et al., 1999, NatureBiotechnology 17: 893-896). Mutagenized DNA molecules that encode activepolypeptides can be recovered from the host cells and rapidly sequencedusing standard methods in the art. These methods allow the rapiddetermination of the importance of individual amino acid residues in apolypeptide.

The polypeptide may be a hybrid polypeptide in which a region of onepolypeptide is fused at the N-terminus or the C-terminus of a region ofanother polypeptide.

The polypeptide may be a fusion polypeptide or cleavable fusionpolypeptide in which another polypeptide is fused at the N-terminus orthe C-terminus of the polypeptide of the present invention. A fusionpolypeptide is produced by fusing a polynucleotide encoding anotherpolypeptide to a polynucleotide of the present invention. Techniques forproducing fusion polypeptides are known in the art, and include ligatingthe coding sequences encoding the polypeptides so that they are in frameand that expression of the fusion polypeptide is under control of thesame promoter(s) and terminator. Fusion polypeptides may also beconstructed using intein technology in which fusion polypeptides arecreated post-translationally (Cooper et al., 1993, EMBO J. 12:2575-2583; Dawson et al., 1994, Science 266: 776-779).

A fusion polypeptide can further comprise a cleavage site between thetwo polypeptides. Upon secretion of the fusion protein, the site iscleaved releasing the two polypeptides. Examples of cleavage sitesinclude, but are not limited to, the sites disclosed in Martin et al.,2003, J. Ind. Microbiol. Biotechnol. 3: 568-576; Svetina et al., 2000,J. Biotechnol. 76: 245-251; Rasmussen-Wilson et al., 1997, Appl.Environ. Microbiol. 63: 3488-3493; Ward et al., 1995, Biotechnology 13:498-503; and Contreras et al., 1991, Biotechnology 9: 378-381; Eaton etal., 1986, Biochemistry 25: 505-512; Collins-Racie et al., 1995,Biotechnology 13: 982-987; Carter et al., 1989, Proteins: Structure,Function, and Genetics 6: 240-248; and Stevens, 2003, Drug DiscoveryWorld 4: 35-48.

The polypeptide may be expressed by a recombinant DNA sequencecontaining the coding for a His-tag or HQ-tag to give, after anypost-translational modifications, the mature polypeptide containing allor part of the His- or HQ-tag. The HQ-tag, having the sequence —RHQHQHQ,may be fully or partly cleaved off the polypeptide during thepost-translational modifications resulting in for example the additionalamino acids —RHQHQ attached to the N-terminal of the mature polypeptide.The His-tag, having the sequence —RPHHHHHH, may be fully or partlycleaved off the polypeptide during the post-translational modificationsresulting in additional amino acids such as —RPHHHHH, —RPHHHH, —RPHHH,—RPHH, —RPH, —RP or —R attached to the N-terminal of the maturepolypeptide.

Examples of conservative substitutions are within the groups of basicamino acids (arginine, lysine and histidine), acidic amino acids(glutamic acid and aspartic acid), polar amino acids (glutamine andasparagine), hydrophobic amino acids (leucine, isoleucine and valine),aromatic amino acids (phenylalanine, tryptophan and tyrosine), and smallamino acids (glycine, alanine, serine, threonine and methionine). Aminoacid substitutions that do not generally alter specific activity areknown in the art and are described, for example, by H. Neurath and R. L.Hill, 1979, In, The Proteins, Academic Press, New York. Commonsubstitutions are Ala/Ser, Val/Ile, Asp/Glu, Thr/Ser, Ala/Gly, Ala/Thr,Ser/Asn, Ala/Val, Ser/Gly, Tyr/Phe, Ala/Pro, Lys/Arg, Asp/Asn, Leu/Ile,Leu/Val, Ala/Glu, and Asp/Gly.

Alternatively, the amino acid changes are of such a nature that thephysico-chemical properties of the polypeptides are altered. Forexample, amino acid changes may improve the thermal stability of thepolypeptide, alter the substrate specificity, change the pH optimum, andthe like.

Essential amino acids in a polypeptide can be identified according toprocedures known in the art, such as site-directed mutagenesis oralanine-scanning mutagenesis (Cunningham and Wells, 1989, Science 244:1081-1085). In the latter technique, single alanine mutations areintroduced at every residue in the molecule, and the resultant mutantmolecules are tested for cellulase and/or xanthan lyase activity toidentify amino acid residues that are critical to the activity of themolecule. See also, Hilton et al., 1996, J. Biol. Chem. 271: 4699-4708.The active site of the enzyme or other biological interaction can alsobe determined by physical analysis of structure, as determined by suchtechniques as nuclear magnetic resonance, crystallography, electrondiffraction, or photoaffinity labelling, in conjunction with mutation ofputative contact site amino acids. See, for example, de Vos et al.,1992, Science 255: 306-312; Smith et al., 1992, J. Mol. Biol. 224:899-904; Wlodaver et al., 1992, FEBS Lett. 309: 59-64. The identity ofessential amino acids can also be inferred from an alignment with arelated polypeptide.

Single or multiple amino acid substitutions, deletions, and/orinsertions can be made and tested using known methods of mutagenesis,recombination, and/or shuffling, followed by a relevant screeningprocedure, such as those disclosed by Reidhaar-Olson and Sauer, 1988,Science 241: 53-57; Bowie and Sauer, 1989, Proc. Natl. Acad. Sci. USA86: 2152-2156; WO 95/17413; or WO 95/22625. Other methods that can beused include error-prone PCR, phage display (e.g., Lowman et al., 1991,Biochemistry 30: 10832-10837; U.S. Pat. No. 5,223,409; WO 92/06204), andregion-directed mutagenesis (Derbyshire et al., 1986, Gene 46: 145; Neret al., 1988, DNA 7: 127).

Mutagenesis/shuffling methods can be combined with high-throughput,automated screening methods to detect activity of cloned, mutagenizedpolypeptides expressed by host cells (Ness et al., 1999, NatureBiotechnology 17: 893-896). Mutagenized DNA molecules that encode activepolypeptides can be recovered from the host cells and rapidly sequencedusing standard methods in the art. These methods allow the rapiddetermination of the importance of individual amino acid residues in apolypeptide.

Sources of GH9 Endoglucanases Having Activity on Xanthan Gum Pretreatedwith Xanthan Lyase and Polypeptides Having Xanthan Lyase Activity

A GH9 endoglucanase having activity on xanthan gum pretreated with axanthan lyase of the present invention and polypeptides having xanthanlyase activity may be obtained from microorganisms of any genus. Forpurposes of the present invention, the term “obtained from” as usedherein in connection with a given source shall mean that the polypeptideencoded by a polynucleotide is produced by the source or by a strain inwhich the polynucleotide from the source has been inserted. In oneaspect, the polypeptide obtained from a given source is secretedextracellularly.

In one aspect, the polypeptide is from a bacterium of the class Bacilli,such as from the order Bacillales, or from the family Paenibacillaceae,or from the genus Paeniobacillus or from the species Paeniobacillus suchas Paeniobacillus sp NN062047, Paeniobacillus sp NN062250,Paeniobacillus sp NN062253, Paeniobacillus sp NN018054, Paeniobacillussp NN062046, Paeniobacillus sp NN062408, Paeniobacillus sp NN062332,Paeniobacillus sp NN062147 or Paeniobacillus sp NN062193.

In another aspect, the polypeptide from a bacterium of the classActinobacteria, such as from the order Actinomycetales, or from thefamily Microbacteriaceae, or from the genus Microbacterium or from thespecies Microbacterium such as Microbacterium testaceum, Microbacteriumsp NN062045, Microbacterium sp NN062148, Microbacterium sp NN062175 orMicrobacterium sp NN062149.

It will be understood that for the aforementioned species, the inventionencompasses both the perfect and imperfect states, and other taxonomicequivalents, e.g., anamorphs, regardless of the species name by whichthey are known. Those skilled in the art will readily recognize theidentity of appropriate equivalents.

Strains of these species are readily accessible to the public in anumber of culture collections, such as the American Type CultureCollection (ATCC), Deutsche Sammlung von Mikroorganismen andZellkulturen GmbH (DSMZ), Centraalbureau Voor Schimmelcultures (CBS),and Agricultural Research Service Patent Culture Collection, NorthernRegional Research Center (NRRL).

The polypeptide may be identified and obtained from other sourcesincluding microorganisms isolated from nature (e.g., soil, composts,water, etc.) or DNA samples obtained directly from natural materials(e.g., soil, composts, water, etc.) using the above-mentioned probes.Techniques for isolating microorganisms and DNA directly from naturalhabitats are well known in the art. A polynucleotide encoding thepolypeptide may then be obtained by similarly screening a genomic DNA orcDNA library of another microorganism or mixed DNA sample. Once apolynucleotide encoding a polypeptide has been detected with theprobe(s), the polynucleotide can be isolated or cloned by utilizingtechniques that are known to those of ordinary skill in the art (see,e.g., Sambrook et al., 1989, supra).

Polynucleotides

The present invention also relates to isolated polynucleotides encodinga polypeptide of the present invention, as described herein.

The techniques used to isolate or clone a polynucleotide are known inthe art and include isolation from genomic DNA or cDNA, or a combinationthereof. The cloning of the polynucleotides from genomic DNA can beeffected, e.g., by using the well known polymerase chain reaction (PCR)or antibody screening of expression libraries to detect cloned DNAfragments with shared structural features. See, e.g., Innis et al.,1990, PCR: A Guide to Methods and Application, Academic Press, New York.Other nucleic acid amplification procedures such as ligase chainreaction (LCR), ligation activated transcription (LAT) andpolynucleotide-based amplification (NASBA) may be used. Thepolynucleotides may be cloned in a strain of Bacillus subtilis or E.Coli, or a related organism and thus, for example, may be an allelic orspecies variant of the polypeptide encoding region of thepolynucleotide.

The term “substantially similar” to thepolypeptide refers to non-naturally occurring forms of the polypeptide.These polypeptides may differ in some engineered way from thepolypeptide isolated from its native source, e.g., variants that differin specific activity, thermostability, pH optimum, or the like. Thevariants may be constructed on the basis of the polynucleotide presentedas the mature polypeptide coding sequence of SEQ ID NO: 1, SEQ ID NO: 3,SEQ ID NO: 9, SEQ ID NO: 11, SEQ ID: NO:13, SEQ ID NO: 15, SEQ ID NO:45, SEQ ID NO: 47, SEQ ID NO: 51, SEQ ID NO: 55, SEQ ID NO: 59, SEQ IDNO: 63, SEQ ID NO: 81, SEQ ID NO: 85, SEQ ID NO: 89, SEQ ID NO: 93, SEQID NO: 97, SEQ ID NO: 105, SEQ ID NO: 109, SEQ ID NO: 113, SEQ ID NO:117, SEQ ID NO: 121, SEQ ID NO: 125, SEQ ID NO: 129, SEQ ID NO: 133 orSEQ ID NO: 137 e.g., a subsequence thereof, and/or by introduction ofnucleotide substitutions that do not result in a change in the aminoacid sequence of the polypeptide, but which correspond to the codonusage of the host organism intended for production of the enzyme, or byintroduction of nucleotide substitutions that may give rise to adifferent amino acid sequence.

Nucleic Acid Constructs

The present invention also relates to nucleic acid constructs comprisinga polynucleotide of the present invention operably linked to one or morecontrol sequences that direct the expression of the coding sequence in asuitable host cell under conditions compatible with the controlsequences.

A polynucleotide may be manipulated in a variety of ways to provide forexpression of the polypeptide. Manipulation of the polynucleotide priorto its insertion into a vector may be desirable or necessary dependingon the expression vector. The techniques for modifying polynucleotidesutilizing recombinant DNA methods are well known in the art.

The control sequence may be a promoter, a polynucleotide that isrecognized by a host cell for expression of a polynucleotide encoding apolypeptide of the present invention. The promoter containstranscriptional control sequences that mediate the expression of thepolypeptide. The promoter may be any polynucleotide that showstranscriptional activity in the host cell including mutant, truncated,and hybrid promoters, and may be obtained from genes encodingextracellular or intracellular polypeptides either homologous orheterologous to the host cell.

Examples of suitable promoters for directing transcription of thenucleic acid constructs of the present invention in a bacterial hostcell are the promoters obtained from the Bacillus amyloliquefaciensalpha-amylase gene (amyQ), Bacillus licheniformis alpha-amylase gene(amyL), Bacillus licheniformis penicillinase gene (penP), Bacillusstearothermophilus maltogenic amylase gene (amyM), Bacillus subtilislevansucrase gene (sacB), Bacillus subtilis xylA and xylB genes,Bacillus thuringiensis cryIIIA gene (Agaisse and Lereclus, 1994,Molecular Microbiology 13: 97-107), E. coli lac operon, E. coli trcpromoter (Egon et al., 1988, Gene 69: 301-315), Streptomyces coelicoloragarase gene (dagA), and prokaryotic beta-lactamase gene (Villa-Kamaroffet al., 1978, Proc. Natl. Acad. Sci. USA 75: 3727-3731), as well as thetac promoter (DeBoer et al., 1983, Proc. Natl. Acad. Sci. USA 80:21-25). Further promoters are described in “Useful proteins fromrecombinant bacteria” in Gilbert et al., 1980, Scientific American 242:74-94; and in Sambrook et al., 1989, supra. Examples of tandem promotersare disclosed in WO 99/43835.

Examples of suitable promoters for directing transcription of thenucleic acid constructs of the present invention in a filamentous fungalhost cell are promoters obtained from the genes for Aspergillus nidulansacetamidase, Aspergillus niger neutral alpha-amylase, Aspergillus nigeracid stable alpha-amylase, Aspergillus niger or Aspergillus awamoriglucoamylase (glaA), Aspergillus oryzae TAKA amylase, Aspergillus oryzaealkaline protease, Aspergillus oryzae triose phosphate isomerase,Fusarium oxysporum trypsin-like protease (WO 96/00787), Fusariumvenenatum amyloglucosidase (WO 00/56900), Fusarium venenatum Daria (WO00/56900), Fusarium venenatum Quinn (WO 00/56900), Rhizomucor mieheilipase, Rhizomucor miehei aspartic proteinase, Trichoderma reeseibeta-glucosidase, Trichoderma reesei cellobiohydrolase I, Trichodermareesei cellobiohydrolase II, Trichoderma reesei endoglucanase I,Trichoderma reesei endoglucanase II, Trichoderma reesei endoglucanaseIII, Trichoderma reesei endoglucanase IV, Trichoderma reeseiendoglucanase V, Trichoderma reesei xylanase I, Trichoderma reeseixylanase II, Trichoderma reesei beta-xylosidase, as well as the NA2-tpipromoter (a modified promoter from an Aspergillus neutral alpha-amylasegene in which the untranslated leader has been replaced by anuntranslated leader from an Aspergillus triose phosphate isomerase gene;non-limiting examples include modified promoters from an Aspergillusniger neutral alpha-amylase gene in which the untranslated leader hasbeen replaced by an untranslated leader from an Aspergillus nidulans orAspergillus oryzae triose phosphate isomerase gene); and mutant,truncated, and hybrid promoters thereof.

In a yeast host, useful promoters are obtained from the genes forSaccharomyces cerevisiae enolase (ENO-1), Saccharomyces cerevisiaegalactokinase (GAL1), Saccharomyces cerevisiae alcoholdehydrogenase/glyceraldehyde-3-phosphate dehydrogenase (ADH1, ADH2/GAP),Saccharomyces cerevisiae triose phosphate isomerase (TPI), Saccharomycescerevisiae metallothionein (CUP1), and Saccharomyces cerevisiae3-phosphoglycerate kinase. Other useful promoters for yeast host cellsare described by Romanos et al., 1992, Yeast 8: 423-488.

The control sequence may also be a transcription terminator, which isrecognized by a host cell to terminate transcription. The terminator isoperably linked to the 3′-terminus of the polynucleotide encoding thepolypeptide. Any terminator that is functional in the host cell may beused in the present invention.

Preferred terminators for bacterial host cells are obtained from thegenes for Bacillus clausii alkaline protease (aprH), Bacilluslicheniformis alpha-amylase (amyL), and Escherichia coli ribosomal RNA(rrnB).

Preferred terminators for filamentous fungal host cells are obtainedfrom the genes for Aspergillus nidulans anthranilate synthase,Aspergillus niger glucoamylase, Aspergillus niger alpha-glucosidase,Aspergillus oryzae TAKA amylase, and Fusarium oxysporum trypsin-likeprotease.

Preferred terminators for yeast host cells are obtained from the genesfor Saccharomyces cerevisiae enolase, Saccharomyces cerevisiaecytochrome C (CYC1), and Saccharomyces cerevisiaeglyceraldehyde-3-phosphate dehydrogenase. Other useful terminators foryeast host cells are described by Romanos et al., 1992, supra.

The control sequence may also be an mRNA stabilizer region downstream ofa promoter and upstream of the coding sequence of a gene which increasesexpression of the gene.

Examples of suitable mRNA stabilizer regions are obtained from aBacillus thuringiensis cryIIIA gene (WO 94/25612) and a Bacillussubtilis SP82 gene (Hue et al., 1995, Journal of Bacteriology 177:3465-3471).

The control sequence may also be a leader, a nontranslated region of anmRNA that is important for translation by the host cell. The leader isoperably linked to the 5′-terminus of the polynucleotide encoding thepolypeptide. Any leader that is functional in the host cell may be used.

Preferred leaders for filamentous fungal host cells are obtained fromthe genes for Aspergillus oryzae TAKA amylase and Aspergillus nidulanstriose phosphate isomerase.

Suitable leaders for yeast host cells are obtained from the genes forSaccharomyces cerevisiae enolase (ENO-1), Saccharomyces cerevisiae3-phosphoglycerate kinase, Saccharomyces cerevisiae alpha-factor, andSaccharomyces cerevisiae alcoholdehydrogenase/glyceraldehyde-3-phosphate dehydrogenase (ADH2/GAP).

The control sequence may also be a polyadenylation sequence, a sequenceoperably linked to the 3′-terminus of the polynucleotide and, whentranscribed, is recognized by the host cell as a signal to addpolyadenosine residues to transcribed mRNA. Any polyadenylation sequencethat is functional in the host cell may be used.

Preferred polyadenylation sequences for filamentous fungal host cellsare obtained from the genes for Aspergillus nidulans anthranilatesynthase, Aspergillus niger glucoamylase, Aspergillus nigeralpha-glucosidase Aspergillus oryzae TAKA amylase, and Fusariumoxysporum trypsin-like protease.

Useful polyadenylation sequences for yeast host cells are described byGuo and Sherman, 1995, Mol. Cellular Biol. 15: 5983-5990.

The control sequence may also be a signal peptide coding region thatencodes a signal peptide linked to the N-terminus of a polypeptide anddirects the polypeptide into the cell's secretory pathway. The 5′-end ofthe coding sequence of the polynucleotide may inherently contain asignal peptide coding sequence naturally linked in translation readingframe with the segment of the coding sequence that encodes thepolypeptide. Alternatively, the 5′-end of the coding sequence maycontain a signal peptide coding sequence that is foreign to the codingsequence. A foreign signal peptide coding sequence may be required wherethe coding sequence does not naturally contain a signal peptide codingsequence. Alternatively, a foreign signal peptide coding sequence maysimply replace the natural signal peptide coding sequence in order toenhance secretion of the polypeptide. However, any signal peptide codingsequence that directs the expressed polypeptide into the secretorypathway of a host cell may be used.

Effective signal peptide coding sequences for bacterial host cells arethe signal peptide coding sequences obtained from the genes for BacillusNCIB 11837 maltogenic amylase, Bacillus licheniformis subtilisin,Bacillus licheniformis beta-lactamase, Bacillus stearothermophilusalpha-amylase, Bacillus stearothermophilus neutral proteases (nprT,nprS, nprM), and Bacillus subtilis prsA. Further signal peptides aredescribed by Simonen and Palva, 1993, Microbiological Reviews 57:109-137.

Effective signal peptide coding sequences for filamentous fungal hostcells are the signal peptide coding sequences obtained from the genesfor Aspergillus niger neutral amylase, Aspergillus niger glucoamylase,Aspergillus oryzae TAKA amylase, Humicola insolens cellulase, Humicolainsolens endoglucanase V, Humicola lanuginosa lipase, and Rhizomucormiehei aspartic proteinase.

Useful signal peptides for yeast host cells are obtained from the genesfor Saccharomyces cerevisiae alpha-factor and Saccharomyces cerevisiaeinvertase. Other useful signal peptide coding sequences are described byRomanos et al., 1992, supra.

The control sequence may also be a propeptide coding sequence thatencodes a propeptide positioned at the N-terminus of a polypeptide. Theresultant polypeptide is known as a proenzyme or propolypeptide (or azymogen in some cases). A propolypeptide is generally inactive and canbe converted to an active polypeptide by catalytic or autocatalyticcleavage of the propeptide from the propolypeptide. The propeptidecoding sequence may be obtained from the genes for Bacillus subtilisalkaline protease (aprE), Bacillus subtilis neutral protease (nprT),Myceliophthora thermophila laccase (WO 95/33836), Rhizomucor mieheiaspartic proteinase, and Saccharomyces cerevisiae alpha-factor.

Where both signal peptide and propeptide sequences are present, thepropeptide sequence is positioned next to the N-terminus of apolypeptide and the signal peptide sequence is positioned next to theN-terminus of the propeptide sequence.

It may also be desirable to add regulatory sequences that regulateexpression of the polypeptide relative to the growth of the host cell.Examples of regulatory systems are those that cause expression of thegene to be turned on or off in response to a chemical or physicalstimulus, including the presence of a regulatory compound. Regulatorysystems in prokaryotic systems include the lac, tac, and trp operatorsystems. In yeast, the ADH2 system or GAL1 system may be used. Infilamentous fungi, the Aspergillus niger glucoamylase promoter,Aspergillus oryzae TAKA alpha-amylase promoter, and Aspergillus oryzaeglucoamylase promoter may be used. Other examples of regulatorysequences are those that allow for gene amplification. In eukaryoticsystems, these regulatory sequences include the dihydrofolate reductasegene that is amplified in the presence of methotrexate, and themetallothionein genes that are amplified with heavy metals. In thesecases, the polynucleotide encoding the polypeptide would be operablylinked with the regulatory sequence.

Expression Vectors

The present invention also relates to recombinant expression vectorscomprising a polynucleotide of the present invention, a promoter, andtranscriptional and translational stop signals. The various nucleotideand control sequences may be joined together to produce a recombinantexpression vector that may include one or more convenient restrictionsites to allow for insertion or substitution of the polynucleotideencoding the polypeptide at such sites. Alternatively, thepolynucleotide may be expressed by inserting the polynucleotide or anucleic acid construct comprising the polynucleotide into an appropriatevector for expression. In creating the expression vector, the codingsequence is located in the vector so that the coding sequence isoperably linked with the appropriate control sequences for expression.

The recombinant expression vector may be any vector (e.g., a plasmid orvirus) that can be conveniently subjected to recombinant DNA proceduresand can bring about expression of the polynucleotide. The choice of thevector will typically depend on the compatibility of the vector with thehost cell into which the vector is to be introduced. The vector may be alinear or closed circular plasmid.

The vector may be an autonomously replicating vector, i.e., a vectorthat exists as an extrachromosomal entity, the replication of which isindependent of chromosomal replication, e.g., a plasmid, anextrachromosomal element, a minichromosome, or an artificial chromosome.The vector may contain any means for assuring self-replication.Alternatively, the vector may be one that, when introduced into the hostcell, is integrated into the genome and replicated together with thechromosome(s) into which it has been integrated. Furthermore, a singlevector or plasmid or two or more vectors or plasmids that togethercontain the total DNA to be introduced into the genome of the host cell,or a transposon, may be used.

The vector preferably contains one or more selectable markers thatpermit easy selection of transformed, transfected, transduced, or thelike cells. A selectable marker is a gene the product of which providesfor biocide or viral resistance, resistance to heavy metals, prototrophyto auxotrophs, and the like.

Examples of bacterial selectable markers are Bacillus licheniformis orBacillus subtilis dal genes, or markers that confer antibioticresistance such as ampicillin, chloramphenicol, kanamycin, neomycin,spectinomycin, or tetracycline resistance. Suitable markers for yeasthost cells include, but are not limited to, ADE2, HIS3, LEU2, LYS2,MET3, TRP1, and URA3. Selectable markers for use in a filamentous fungalhost cell include, but are not limited to, amdS (acetamidase), argB(ornithine carbamoyltransferase), bar (phosphinothricinacetyltransferase), hph (hygromycin phosphotransferase), niaD (nitratereductase), pyrG (orotidine-5′-phosphate decarboxylase), sC (sulfateadenyltransferase), and trpC (anthranilate synthase), as well asequivalents thereof. Preferred for use in an Aspergillus cell areAspergillus nidulans or Aspergillus oryzae amdS and pyrG genes and aStreptomyces hygroscopicus bar gene.

The vector preferably contains an element(s) that permits integration ofthe vector into the host cell's genome or autonomous replication of thevector in the cell independent of the genome.

For integration into the host cell genome, the vector may rely on thepolynucleotide's sequence encoding the polypeptide or any other elementof the vector for integration into the genome by homologous ornon-homologous recombination. Alternatively, the vector may containadditional polynucleotides for directing integration by homologousrecombination into the genome of the host cell at a precise location(s)in the chromosome(s). To increase the likelihood of integration at aprecise location, the integrational elements should contain a sufficientnumber of nucleic acids, such as 100 to 10,000 base pairs, 400 to 10,000base pairs, and 800 to 10,000 base pairs, which have a high degree ofsequence identity to the corresponding target sequence to enhance theprobability of homologous recombination. The integrational elements maybe any sequence that is homologous with the target sequence in thegenome of the host cell. Furthermore, the integrational elements may benon-encoding or encoding polynucleotides. On the other hand, the vectormay be integrated into the genome of the host cell by non-homologousrecombination.

For autonomous replication, the vector may further comprise an origin ofreplication enabling the vector to replicate autonomously in the hostcell in question. The origin of replication may be any plasmidreplicator mediating autonomous replication that functions in a cell.The term “origin of replication” or “plasmid replicator” means apolynucleotide that enables a plasmid or vector to replicate in vivo.

Examples of bacterial origins of replication are the origins ofreplication of plasmids pBR322, pUC19, pACYC177, and pACYC184 permittingreplication in E. coli, and pUB110, pE194, pTA1060, and pAMβ1 permittingreplication in Bacillus.

Examples of origins of replication for use in a yeast host cell are the2 micron origin of replication, ARS1, ARS4, the combination of ARS1 andCEN3, and the combination of ARS4 and CEN6.

Examples of origins of replication useful in a filamentous fungal cellare AMA1 and ANS1 (Gems et al., 1991, Gene 98: 61-67; Cullen et al.,1987, Nucleic Acids Res. 15: 9163-9175; WO 00/24883). Isolation of theAMA1 gene and construction of plasmids or vectors comprising the genecan be accomplished according to the methods disclosed in WO 00/24883.

More than one copy of a polynucleotide of the present invention may beinserted into a host cell to increase production of a polypeptide. Anincrease in the copy number of the polynucleotide can be obtained byintegrating at least one additional copy of the sequence into the hostcell genome or by including an amplifiable selectable marker gene withthe polynucleotide where cells containing amplified copies of theselectable marker gene, and thereby additional copies of thepolynucleotide, can be selected for by cultivating the cells in thepresence of the appropriate selectable agent.

The procedures used to ligate the elements described above to constructthe recombinant expression vectors of the present invention are wellknown to one skilled in the art (see, e.g., Sambrook et al., 1989,supra).

Host Cells

The present invention also relates to recombinant host cells, comprisinga polynucleotide of the present invention operably linked to one or morecontrol sequences that direct the production of a polypeptide of thepresent invention. A construct or vector comprising a polynucleotide isintroduced into a host cell so that the construct or vector ismaintained as a chromosomal integrant or as a self-replicatingextra-chromosomal vector as described earlier. The term “host cell”encompasses any progeny of a parent cell that is not identical to theparent cell due to mutations that occur during replication. The choiceof a host cell will to a large extent depend upon the gene encoding thepolypeptide and its source.

The host cell may be any cell useful in the recombinant production of apolypeptide of the present invention, e.g., a prokaryote or a eukaryote.

The prokaryotic host cell may be any Gram-positive or Gram-negativebacterium.

Gen.Genet. 168: 111-115), competent cell transformation (see, e.g., Youngand Spizizen, 1961, J. Bacteriol. 81: 823-829, or Dubnau andDavidoff-Abelson, 1971, J. Mol. Biol. 56: 209-221), electroporation(see, e.g., Shigekawa and Dower, 1988, Biotechniques 6: 742-751), orconjugation (see, e.g., Koehler and Thorne, 1987, J. Bacteriol. 169:5271-5278). The introduction of DNA into an E. coli cell may be effectedby protoplast transformation (see, e.g., Hanahan, 1983, J. Mol. Biol.166: 557-580) or electroporation (see, e.g., Dower et al., 1988, NucleicAcids Res. 16: 6127-6145). The introduction of DNA into a Streptomycescell may be effected by protoplast transformation, electroporation (see,e.g., Gong et al., 2004, Folia Microbiol. (Praha) 49: 399-405),conjugation (see, e.g., Mazodier et al., 1989, J. Bacteriol. 171:3583-3585), or transduction (see, e.g., Burke et al., 2001, Proc. Natl.Acad. Sci. USA 98: 6289-6294). The introduction of DNA into aPseudomonas cell may be effected by electroporation (see, e.g., Choi etal., 2006, J. Microbiol. Methods 64: 391-397) or conjugation (see, e.g.,Pinedo and Smets, 2005, Appl. Environ. Microbiol. 71: 51-57). Theintroduction of DNA into a Streptococcus cell may be effected by naturalcompetence (see, e.g., Perry and Kuramitsu, 1981, Infect. Immun. 32:1295-1297), protoplast transformation (see, e.g., Catt and Jollick,1991, Microbios 68: 189-207), electroporation (see, e.g., Buckley etal., 1999, Appl. Environ. Microbiol. 65: 3800-3804), or conjugation(see, e.g., Clewell, 1981, Microbiol. Rev. 45: 409-436). However, anymethod known in the art for introducing DNA into a host cell can beused.

The host cell may also be a eukaryote, such as a mammalian, insect,plant, or fungal cell. The host cell may be a fungal cell. “Fungi” asused herein includes the phyla Ascomycota, Basidiomycota,Chytridiomycota, and Zygomycota as well as the Oomycota and allmitosporic fungi (as defined by Hawksworth et al., In, Ainsworth andBisby's Dictionary of The Fungi, 8th edition, 1995, CAB International,University Press, Cambridge, UK).

The fungal host cell may be a yeast cell. “Yeast” as used hereinincludes ascosporogenous yeast (Endomycetales), basidiosporogenousyeast, and yeast belonging to the Fungi Imperfecti (Blastomycetes).Since the classification of yeast may change in the future, for thepurposes of this invention, yeast shall be defined as described inBiology and Activities of Yeast (Skinner, Passmore, and Davenport,editors, Soc. App. Bacteriol. Symposium Series No. 9, 1980).

The fungal host cell may be a filamentous fungal cell. “Filamentousfungi” include all filamentous forms of the subdivision Eumycota andOomycota (as defined by Hawksworth et al., 1995, supra). The filamentousfungi are generally characterized by a mycelial wall composed of chitin,cellulose, glucan, chitosan, mannan, and other complex polysaccharides.Vegetative growth is by hyphal elongation and carbon catabolism isobligately aerobic. In contrast, vegetative growth by yeasts such asSaccharomyces cerevisiae is by budding of a unicellular thallus andcarbon catabolism may be fermentative.

Suitable procedures fortransformation of Aspergillus and Trichoderma host cells are describedin EP 238023, Yelton et al., 1984, Proc. Natl. Acad. Sci. USA 81:1470-1474, and Christensen et al., 1988, Bio/Technology 6: 1419-1422.Suitable methods for transforming Fusarium species are described byMalardier et al., 1989, Gene 78: 147-156, and WO 96/00787.

Methods of Production

The present invention also relates to methods of producing a polypeptideof the present invention, comprising (a) cultivating a cell, which inits wild-type form produces the polypeptide, under conditions conducivefor production of the polypeptide; and (b) recovering the polypeptide.In a preferred aspect, the cell is a Paenibacillus cell, or aMicrobacterium cell.

The present invention also relates to methods of producing a polypeptideof the present invention, comprising (a) cultivating a recombinant hostcell of the present invention under conditions conducive for productionof the polypeptide; and (b) recovering the polypeptide.

The host cells are cultivated in a nutrient medium suitable forproduction of the polypeptide using methods known in the art. Forexample, the cell may be cultivated by shake flask cultivation, orsmall-scale or large-scale fermentation (including continuous, batch,fed-batch, or solid state fermentations) in laboratory or industrialfermentors performed in a suitable medium and under conditions allowingthe polypeptide to be expressed and/or isolated. The cultivation takesplace in a suitable nutrient medium comprising carbon and nitrogensources and inorganic salts, using procedures known in the art. Suitablemedia are available from commercial suppliers or may be preparedaccording to published compositions (e.g., in catalogues of the AmericanType Culture Collection). If the polypeptide is secreted into thenutrient medium, the polypeptide can be recovered directly from themedium. If the polypeptide is not secreted, it can be recovered fromcell lysates.

The polypeptide may be detected using methods known in the art that arespecific for the polypeptides such as methods for determining celluloseor xanthan lyase activity. These detection methods include, but are notlimited to, use of specific antibodies, formation of an enzyme product,or disappearance of an enzyme substrate. For example, an enzyme assaymay be used to determine the activity of the polypeptide.

The polypeptide may be recovered using methods known in the art. Forexample, the polypeptide may be recovered from the nutrient medium byconventional procedures including, but not limited to, collection,centrifugation, filtration, extraction, spray-drying, evaporation, orprecipitation.

The polypeptide may be purified by a variety of procedures known in theart including, but not limited to, chromatography (e.g., ion exchange,affinity, hydrophobic, chromatofocusing, and size exclusion),electrophoretic procedures (e.g., preparative isoelectric focusing),differential solubility (e.g., ammonium sulfate precipitation),SDS-PAGE, or extraction (see, e.g., Protein Purification, Janson andRyden, editors, VCH Publishers, New York, 1989) to obtain substantiallypure polypeptides.

In an alternative aspect, the polypeptide is not recovered, but rather ahost cell of the present invention expressing the polypeptide is used asa source of the polypeptide.

The present invention also relates to a fermentation broth formulationor a cell composition comprising a polypeptide of the present invention.The fermentation broth product further comprises additional ingredientsused in the fermentation process, such as, for example, cells(including, the host cells containing the gene encoding the polypeptideof the present invention which are used to produce the polypeptide ofinterest), cell debris, biomass, fermentation media and/or fermentationproducts. In some embodiments, the composition is a cell-killed wholebroth containing organic acid(s), killed cells and/or cell debris, andculture medium.

The term “fermentation broth” as used herein refers to a preparationproduced by cellular fermentation that undergoes no or minimal recoveryand/or purification. For example, fermentation broths are produced whenmicrobial cultures are grown to saturation, incubated undercarbon-limiting conditions to allow protein synthesis (e.g., expressionof enzymes by host cells) and secretion into cell culture medium. Thefermentation broth can contain unfractionated or fractionated contentsof the fermentation materials derived at the end of the fermentation.Typically, the fermentation broth is unfractionated and comprises thespent culture medium and cell debris present after the microbial cells(e.g., filamentous fungal cells) are removed, e.g., by centrifugation.In some embodiments, the fermentation broth contains spent cell culturemedium, extracellular enzymes, and viable and/or nonviable microbialcells.

Hydrotropes

A hydrotrope is a compound that solubilises hydrophobic compounds inaqueous solutions (or oppositely, polar substances in a non-polarenvironment). Typically, hydrotropes have both hydrophilic and ahydrophobic character (so-called amphiphilic properties as known fromsurfactants); however the molecular structure of hydrotropes generallydo not favor spontaneous self-aggregation, see e.g. review by Hodgdonand Kaler (2007), Current Opinion in Colloid & Interface Science 12:121-128. Hydrotropes do not display a critical concentration above whichself-aggregation occurs as found for surfactants and lipids formingmiceller, lamellar or other well defined meso-phases. Instead, manyhydrotropes show a continuous-type aggregation process where the sizesof aggregates grow as concentration increases. However, many hydrotropesalter the phase behavior, stability, and colloidal properties of systemscontaining substances of polar and non-polar character, includingmixtures of water, oil, surfactants, and polymers. Hydrotropes areclassically used across industries from pharma, personal care, food, totechnical applications. Use of hydrotropes in detergent compositionsallow for example more concentrated formulations of surfactants (as inthe process of compacting liquid detergents by removing water) withoutinducing undesired phenomena such as phase separation or high viscosity.

The detergent may contain 0-5% by weight, such as about 0.5 to about 5%,or about 3% to about 5%, of a hydrotrope. Any hydrotrope known in theart for use in detergents may be utilized. Non-limiting examples ofhydrotropes include sodium benzene sulfonate, sodium p-toluene sulfonate(STS), sodium xylene sulfonate (SXS), sodium cumene sulfonate (SCS),sodium cymene sulfonate, amine oxides, alcohols and polyglycolethers,sodium hydroxynaphthoate, sodium hydroxynaphthalene sulfonate, sodiumethylhexyl sulfate, and combinations thereof.

In a dish wash detergent, the level of builder is typically40-65%, particularly 50-65%. The builder and/or co-builder mayparticularly be a chelating agent that forms water-soluble complexeswith Ca and Mg. Any builder and/or co-builder known in the art for usein laundry detergents may be utilized. Non-limiting examples of buildersinclude zeolites, diphosphates (pyrophosphates), triphosphates such assodium triphosphate (STP or STPP), carbonates such as sodium carbonate,soluble silicates such as sodium metasilicate, layered silicates (e.g.,SKS-6 from Hoechst), ethanolamines such as 2-aminoethan-1-ol (MEA),diethanolamine (DEA, also known as iminodiethanol), triethanolamine(TEA, also known as 2,2′,2″-nitrilotriethanol), and carboxymethyl inulin(CMI), and combinations thereof.

Use in the Fracturing of a Subterranean Formation (Oil Drilling)

Hydraulic fracturing is used to create subterranean fractures thatextend from the borehole into rock formation in order to increase therate at which fluids can be produced by the formation. Generally, a highviscosity fracturing fluid is pumped into the well at sufficientpressure to fracture the subterranean formation. In order to maintainthe increased exposure to the formation, a solid proppant is added tothe fracturing fluid which is carried into the fracture by the highpressure applied to the fluid. Once the high viscosity fracturing fluidhas carried the proppant into the formation, breakers are used to reducethe fluid's viscosity which allows the proppant to settle into thefracture and thereby increase the exposure of the formation to the well.Breakers work by reducing the molecular weight of the polymers, thus‘breaking’ or degrading the polymer. The fracture then becomes a highpermeability conduit for fluids and gas to be produced back to the well.Such processes are further disclosed in U.S. Pat. Nos. 7,360,593,5,806,597, 5,562,160, 5,201,370 and 5,067,566.

Thus the invention relates to the use of GH9 endoglucanases of theinvention as enzyme breakers. The invention also relates to the use ofxanthan lyases of the invention as enzyme breakers. An embodiment of theinvention is the use of GH9 endoglucanases of the invention togetherwith xanthan lyases of the invention as enzyme breakers.

Accordingly, the invention provides a method for breaking xanthan gum ina well bore comprising: (i) blending together a gellable fracturingfluid comprising aqueous fluid, one or more hydratable polymers,suitable cross-linking agents for cross-linking the hydratable polymerto form a polymer gel and one or more enzymes of the invention (i.e. theenzyme breaker); (ii) pumping the cross-linked polymer gel into the wellbore under sufficient pressure to fracture the surrounding formation;and (iii) allowing the enzyme breaker to degrade the cross-linkedpolymer to reduce the viscosity of the fluid so that the fluid can bepumped from the formation back to the well surface. As such, the GH9endoglucanases of the invention can be used to control the viscosity offracturing fluids. Furthermore, the xanthan lyases of the invention canbe used to control the viscosity of fracturing fluids. In an embodiment,one or more GH9 endoglucanases of the invention together with one ormore xanthan lyases of the invention can be used to control theviscosity of fracturing fluids.

The enzyme breaker of the present invention may be an ingredient of afracturing fluid or a breaker-crosslinker-polymer complex which furthercomprises a hydratable polymer and a crosslinking agent. The fracturingfluid or complex may be a gel or may be gellable. The complex is usefulin a method for using the complex in a fracturing fluid to fracture asubterranean formation that surrounds a well bore by pumping the fluidto a desired location within the well bore under sufficient pressure tofracture the surrounding subterranean formation. The complex may bemaintained in a substantially non-reactive state by maintaining specificconditions of pH and temperature, until a time at which the fluid is inplace in the well bore and the desired fracture is completed. Once thefracture is completed, the specific conditions at which the complex isinactive are no longer maintained. When the conditions changesufficiently, the complex becomes active and the breaker begins tocatalyze polymer degradation causing the fracturing fluid to becomesufficiently fluid to be pumped from the subterranean formation to thewell surface.

When a well is drilled, reservoir drilling fluid (RDF) is circulatedwithin the drilling equipment to cool down and clean the drill bit,remove the drill cuttings out of the well bore, reduce friction betweenthe drill string and the sides of the borehole, and form a filtercake inorder to prevent fluid leak off into the formation. The driving forcefor the formation of the filtercake is the higher wellbore pressureapplied to maintain the borehole stability. This filtercake restrictsthe inflow of reservoir fluids into the wellbore during the drillingprocess and placement of the completion. If the filtercake damage thatis created during the drilling process is not removed prior to or duringcompletion of the well, a range of issues can arise when the well is puton production, i.e., completion equipment failures and impairedreservoir productivity.

Drilling fluid (mud), also called reservoir drilling fluid (RDF), can besynthetic/oil based or water based. To minimize invasion of the drillingfluid into the formation, both oil based and water based mud filtercakestypically contain a bridging or weighting agent, usually particles ofcalcium carbonate, barite or a mixture of the two, that bridge at thepore throats of the formation and thereby form a relatively lowpermeability filtercake. Both oil based and water based mud filtercakesalso contain solids called cuttings that have been picked up duringdrilling, as opposed to the bridging/weighting agents that are added inthe formulation of the drilling fluid. These solids can be quartz(sand), silts and/or shales, depending on the reservoir formation aswell as the formations traversed by the drilling path to the reservoir.In addition, oil based drilling muds contain water droplets that becometrapped in the pore space of the filtercake, while water based mudfiltercakes contain polymers, such as starch and xanthan gum, and otherinorganic salts.

The formation of a mud filtercake is often necessary for drilling,particularly in unconsolidated formations with wellbore stabilityproblems and typically high permeabilities. The filtercake is thentreated with various chemicals, such as chelants or acids to dissolvethe calcite component; and/or enzymes or oxidizers to degrade thepolymer component to recover permeability.

In one aspect, the invention provides a method for degrading xanthan gumwherein xanthan gum is used in fracturing of a subterranean formationperpetrated by a well bore by applying a composition comprising one ofmore enzymes of the invention. The method can include the steps of: (i)pumping a treatment fluid comprising one or more enzymes of theinvention into the borehole in contact with the filtercake to be removedto establish a differential pressure between the treatment fluid and theformation adjacent the filtercake and (ii) evenly propagating treatmentof the filtercake during the differential pressure period to delaybreakthrough by the treatment fluid.

In one embodiment, the method can include establishing permeabilitythrough the treated filtercake between the formation and the borehole.In another embodiment, the filtercake can include drilling solids andclays, and may be formed from an aqueous drilling fluid. If desired, thetreatment fluid for treating the aqueous drilling fluid filtercake canalso include an oxidizer and/or a chelant, or it can be substantiallyfree of chelant and oxidizer additives. In another example, thefiltercake can be formed from an oil or invert emulsion drilling fluid.If desired, the treatment fluid for treating the oil or invert emulsiondrilling fluid filtercake can also include a mutual solvent, awater-wetting agent or a combination thereof to disperse hydrophobiccomponents in the filtercake.

In one embodiment, the treatment fluid comprises one or more GH9endoglucanases of the invention. In another embodiment, the treatmentfluid comprises one or more xanthan lyases of the invention. In apreferred embodiment, the treatment fluid comprises one or more GH9endoglucanases and one or more xanthan lyases of the invention.

Method of Degrading Xanthan Gum Wherein the Xanthan Gum is a Componentin Borehole Filtercake

In one aspect, the invention provides a method for cleaning boreholefiltercake, comprising polymers, such as xanthan gum and drilling fluidsolids once the filtercake has been pumped to the surface. Drilling mudis pumped from mud pits to the drill bit and then back out to thesurface, carrying out amongst other things crushed or cut rock(cuttings) in the process. The cuttings are filtered out and the mud isreturned to the mud pits where fines can settle and/or chemicals orenzymes (breakers) can be added.

The method for degrading xanthan gum wherein the xanthan gum is acomponent in borehole filtercake can include the steps of (i) treatingthe borehole filtercake with a treatment fluid comprising one or moreenzymes of the invention and (ii) separating the solids from the fluids.In one embodiment, the treatment fluid comprises one or more GH9endoglucanases of the invention. In another embodiment, the treatmentfluid comprises one or more xanthan lyases of the invention. In apreferred embodiment, the treatment fluid comprises one or more GH9endoglucanases of the invention and one or more xanthan lyases of theinvention.

The borehole filtercake may be treated in mud pits with one or moreenzymes of the invention and the drilling fluid can be re-circulated.Alternatively, once the filtercake has been treated with one or moreenzymes of the invention, the solids and fluid are separated usingsolid-liquid separation processes, such as centrifugation.

The present invention is further described by the following examplesthat should not be construed as limiting the scope of the invention.

Wash Assays Automatic Mechanical Stress Assay (AMSA) for Laundry

In order to assess the wash performance in laundry washing experimentsare performed, using the Automatic Mechanical Stress Assay (AMSA). Withthe AMSA, the wash performance of a large quantity of small volumeenzyme-detergent solutions can be examined. The AMSA plate has a numberof wells for test solutions and a lid firmly squeezing the laundrysample, the textile to be washed against all the slot openings. Duringthe washing time, the plate, test solutions, textile and lid arevigorously shaken at the controlled temperature to bring the testsolution in contact with the textile and apply mechanical stress in aregular, periodic oscillating manner. For further description seeWO02/42740 especially the paragraph “Special method embodiments” at page23-24.

The wash performance is measured as the brightness of the colour of thetextile washed. Brightness can also be expressed as the intensity of thelight reflected from the sample when illuminated with white light. Whenthe sample is stained the intensity of the reflected light is lower,than that of a clean sample. Therefore the intensity of the reflectedlight can be used to measure wash performance.

Colour measurements are made with a professional flatbed scanner (KodakiQsmart, Kodak, Midtager 29, DK-2605 Brøndby, Denmark, or EpsonExpression 10000XL, Epson Danmark, Transformervej 6, 2730 Herlev,Denmark), which is used to capture an image of the washed textile.

To extract a value for the light intensity from the scanned images,24-bit pixel values from the image are converted into values for red,green and blue (RGB). The intensity value (Int) is calculated by addingthe RGB values together as vectors and then taking the length of theresulting vector:

Int=√{square root over (r ² +g ² +b ²)}

Mini Launder-O-Meter (MiniLOM) Assay

The miniLOM assay is a small scale version of the Launder-O-Meter (LOM).It can be used to determine the “enzyme detergency benefit”. A miniLOMbasically consists of closed test tubes being rotated in a heatingcabinet at a given time and temperature. Each test tube constitutes onesmall washing machine and during an experiment, each will contain asolution of a specific detergent/enzyme system to be tested along withthe soiled and unsoiled fabrics it is tested on. Mechanical stress isachieved by the tubes being rotated and by including metal balls in thetube.

The small scale model wash system is mainly used in testing ofdetergents and enzymes at European wash conditions.

Evaluation of Stains from Mini-LOM

Wash performance is expressed as a remission value (Rem). After washingand rinsing the swatches were spread out flat and allowed to air dry atroom temperature over night. All washes are evaluated shall be evaluatedday 2 after wash. Light reflectance evaluations of the swatches weredone using a Macbeth Color Eye 7000 reflectance spectrophotometer withvery small aperture. The measurements were made without UV in theincident light and remission at 460 nm was extracted. Measurements weremade on washed swatches. The test swatch to be measured was placed ontop of another swatch of same type and colour (twin swatch). With onlyone swatch of each kind per beaker, a swatch from a replicate wash wasused in this way. The enzyme performance can be seen by comparing theremission value of using no enzyme to the remission value using one ormore enzymes. The higher the remission vale, the better the cleaningeffect.

Activity Assays Xanthan Lyase Activity Assay (Xanthan Lyase SpecificAssay)

0.8 mL 100 mM HEPES buffer, pH 6.0 was mixed with 0.2 mL Xanthan gum (5mg/mL) dissolved in water in a 1 mL 1 cm cuvette. The cuvette wasinserted into a spectrophotometer (Agilent G1103A 8453A, CA, USA) withtemperature control set at 40° C. The solution was pre-incubated for 10min and 0.1 mL sample was added and the solution was mixed by aspiringand dispensing the solution for at least 5 times using a pipette. Totalreaction volume was 1.1 mL. Absorbance at 235 nm was collected for 10min using a 30 sec measuring interval. Initial activity was calculatedby using the software (UV-Visible Chemstation Rev A.10.01 [81],Agilent).

Example 5 Purification of the GH9 and Xanthan Lyase Protein

A Bacillus subtilis strain was constructed as described in examples 2and 4 to express the protein to the culture medium. The culture brothwas centrifuged (17.696×g, 30 min) and the supernatant was carefullydecanted from the precipitate. The supernatant was filtered through aNalgene 0.2 μm filtration unit in order to remove the rest of theBacillus host cells.

The volume was reduced using a Filtron system with 10K cut off filter.The volume was reduced to approx 80 mL, followed by addition of BufferA: 50 mM TRIS+10 mM Imidazole pH 8.0 to the sample. The pH on the samplewas adjusted to 8 and applied to a Ni-NTA Superflow column (QIAGEN)equilibrated in: Buffer A. After loading, the column is washed withBuffer A for 3 column volumes (CV). Then a step gradient to 100% BufferB: Buffer B: 50 mM MES+10 mM Imidazole pH 7.0 was applied andconsecutively a second gradient is applied up to 100% Buffer C: 50 mMMES+1 M Imidazole pH 7.0 in 4 CV. All the positive fractions are run onSDS-PAGE and the respective proteins are identified by the bands. Thefractions containing XL or GH9 respectively were pooled and desaltedinto Buffer Tris 20 mM pH 7.0.

For further purification the respective pool was loaded into aQ-Sepharose Ion Exchange column (GE Healthcare) equilibrated in 20 mMTris pH 7.0. After loading, the protein was eluted using 0-100% 20 mMTris+1M NaCl, pH 7.0. The positive fractions were run on a SDS-PAGE Geland desalted into 20 mM Tris pH 7.0.

The concentration of the purified proteins was determined by Absorbanceat 280 using the respective extinction coefficients calculated from thededuced amino acids sequences of the mature proteins.

Example 6 Activity Screening of Xanthan Lyase and GH9 on Xanthan GumXanthan Lyase Activity

Xanthan lyase activity was determined as described above on the purifiedxanthan lyase protein. The data is presented in the table 5 below.

TABLE 5 Specific Activity of Xanthan Lyase of SEQ ID NO: 8 Conc xanthanlyase Initial activity Specific activity in cuvette (μg/mL) (mAU/min)(mAU/min/mg enzyme) 0.291 17.274 4907 0.582 34.98 4969 1.455 94.32 5359

The data shows that the xanthan lyase had activity on xanthan gum.

Reducing Ends

The method used to determine the amount of reducing ends produced wasthe 2,2′ bicinchoninic acid assay (BCA) as described in Murphy et al.,2012, J. Biol. Chem. 287: 1252-1260 and adapted from Zhang et al, 2005,Biomacromolecules 6: 1510-1515 and Dubois et al, 1956, Anal. Chem. 28:350-356. Quantification of reducing ends was based on a glucose standardcurve. Appropriate substrate and enzyme controls were included andcorrected for in each analysis. Appropriate dilutions were used toensure samples were within the glucose calibration curve range. Theresults are shown in table 7 below.

Viscosity Reduction

The viscosity measurements were performed using the Novozymes-developedviscosity pressure assay described in WO2011/107472. 100 μL of each 1 mLhydrolysis or control was the sample size. Results presented are theaverage of three measurements and are shown in table 6 below.

Hydrolysis

The hydrolysis conditions were as follows: 40° C., 0.25% xanthan gum(XG) in 50 mM MES buffer+0.01% triton x-100 pH 7.0. Enzyme was addedupon thermal equilibration. Prior to use all enzymes were buffer changedto the MES buffer using NAP 5 columns (GE Healthcare).

Enzyme Doses

The purified enzyme preparations of example 5 were used for the analysisin following concentrations:

GH9 (SEQ ID NO: 6): 7.25 mg/L

Xanthan lyase (SEQ ID NO: 8): 40 μg/L

The above results from table 5 show that combination of xanthan lyaseand GH9 can degrade xanthan gum by reducing the viscosity of the media.These results are in accordance with the results obtained from thereducing ends assay, shown in table 6, which shows that the number ofreducing ends increases by the addition of xanthan lyase or xanthanlyase+GH 9, since the xanthan gum is degraded by the enzymes.

Example 7 Demonstration of Synergy Between GH9 Endoglucanase and XanthanLyase

A method using liquid chromatography was used to demonstrate thede-polymerizing effect of GH9 endoglucanase and xanthan lyase, having onxanthan gum. For this example the His-tagged xanthan lyase having SEQ IDNO: 8 and the His-tagged GH9 endoglucanase having SEQ ID NO: 6 wereused. The enzymes were purified as described in example 5.

Substrate mixture consisting of 0.25% (w/v) xanthan gum (Keltron) in thereaction buffer 100 mM HEPES buffer, pH 6.0 supplemented with 0.01%(w/v) Triton-X was mixed with 0.02 mg/mL xanthan lyase and 0.02 mg/mLGH9. 50 μL samples were withdrawn at fixed time point and the sampleswere diluted with 150 μL HEPES buffer, pH 6.0. The sample wasimmediately injected using a 100 μL sample loop and separated on a 26 mLSuperdex S200 column (GE Heathcare, Uppsala, Sweden). The system used inthis experiment was an ÄKTA Explorer (GE heathcare) placed in a coldroom (+4° C.). Separation of polysaccharides was conducted at a flowrate of 0.7 mL/min and using 0.1 M HEPES, pH 7.0 buffer. Absorbance at235 nm was monitored to detect the double bond of the xanthan lyasereaction product. Two peaks could be observed in the chromatogramseluting at retention volumes 9 and 19 mL. A control sample consisting of0.02 mg/mL xanthan lyase and 0.25% (w/v) xanthan gum incubated for 3 hin the reaction buffer only gave rise to a peak with retention volume of9 mL. Thus, the peak appearing at 9 mL corresponded to xanthan lyasetreated xanthan gum. Over time the 9 mL peak decreased while the peakeluting at 19 mL increased in size. The results are presented in table 8below.

TABLE 8 Chromatographic results of GH9 (SEQ ID NO: 6) and Xanthan Lyase(SEQ ID NO: 8) on xanthan gum Peak height 9 mL Peak height 19 mL Time(min) (mAU) (mAU) 3 36 5 40 20 15 85 11 20

The data indicated that the combination of xanthan lyase and the GH9endoglucanase can degrade xanthan gum to smaller xanthan gum derivedoligosaccharides.

Example 8 Specific Activity of Xanthan Lyase Treated Xanthan Gum Vs CMC

The method used to determine the specific activity for a GH9endoglucanase was the p-hydroxybenzoic acid method (PHBAH). For thisexample the His-tagged GH9 endoglucanase derived from Paenibacillus sp.and having the sequence of SEQ ID NO: 6 was used.

Quantification of reducing ends was based on a glucose standard curve.The specific activity on carboxymethyl-cellulose 7LF (Hercules) wasdetermined by using a substrate concentration of 1% w/v. The specificactivity on xanthan lyase treated xanthan gum (prepared according toNankai et al. (1999) from the source Keltran) was determined using a0.25% w/v solution. Assay buffer was 0.1 M HEPES, pH 7.0. 1.5 mLsubstrate dissolved in the assay buffer was pre-heated in glass tubesfor 5 min. 0.5 mL appropriate enzyme dilution was added and the samplewas mixed by a vortex for 10 sec. The samples were incubated for 20 minat 40° C. The enzymatic reaction was terminated by adding 1.0 mL stopreagent consisting of 1.5 g PHBAH, 5 g K/Na tartrate dissolved in 100 mL2% w/v NaOH. The samples were boiled for 10 min and 200 μL weretransferred from each tube to a 96-hole microtiter plate. Absorbance at410 nm was collected. Absorbance values were converted to IU by usingthe glucose standard curve. One IU is defined as the release of 1 μmolglucose equivalent formed per min at 40° C. and pH 7.0. The results areshown in table 9 below.

TABLE 9 Specific activity of the GH9 (SEQ ID NO: 6) on CMC compared toxanthan lyase treated xanthan gum Substrate Specific activity (IU/mg)CMC 2.1 Xanthan lyase treated xanthan gum 41.5

Two synthetic oligonucleotide primers shown below were designed to PCRamplify the xanthan lyase gene, having SEQ ID NO: 4, from the genomicDNA prepared from Paenibacillus sp. NN018054. An IN-FUSION™ Cloning Kit(BD Biosciences, Palo Alto, Calif., USA) was used to clone the fragmentdirectly into the expression vector pDau109 (WO 2005/042735).

Bold letters represent gene sequence. The underlined sequence ishomologous to the insertion sites of pDau109.

An MJ Research PTC-200 DNA engine was used to perform the PCR reaction.A Phusion® High-Fidelity PCR Kit (Finnzymes Oy, Espoo, Finland) was usedfor the PCR amplification. The PCR reaction was composed of 4 μl of 5×GCbuffer (Finnzymes Oy, Espoo, Finland), 0.4 μl of dNTPs (10 mM), 0.2 μlof Phusion® DNA polymerase (0.2 units/μl) (Finnzymes Oy, Espoo,Finland), 1 μl of primer F-C3AQX (10 μM), 1 μl of primer R-C3AQX (10μM), 0.5 μl of genomic DNA (100 ng/μl), and 12.9 μl of deionized waterin a total volume of 20 μl. The PCR conditions were 1 cycle at 98° C.for 1 minute. 30 cycles each at 98° C. for 10 seconds and 72° C. for 1.5minutes; and 1 cycle at 72° C. for 5 minutes. The sample was then heldat 10° C. until removed from the PCR machine.

The reaction products were isolated by 1.0% agarose gel electrophoresisusing 40 mM Tris base, 20 mM sodium acetate, 1 mM disodium EDTA (TAE)buffer where a 2283 bp product band was excised from the gel andpurified using an illustra GFX® PCR DNA and Gel Band Purification Kit(GE Healthcare Life Sciences, Brondby, Denmark) according to themanufacturer's instructions. The fragment was then cloned into Mlu I andHind III digested pDau109 (WO 2005/042735) using an IN-FUSION™ CloningKit resulting in plasmid pC3AQX. Cloning of the C3AQX gene into MluI-Hind III digested pDau109 resulted in the transcription of thePaenibacillus sp-18054 C3AQX gene under the control of a NA2-tpi doublepromoter. The nucleotide sequence and deduced amino acid sequence of thePaenibacillus sp-18054 xanthan lyase C3AQX gene is shown in SEQ ID NO:45 and SEQ ID NO: 46, respectively.

The cloning protocol was performed according to the IN-FUSION™ CloningKit instructions generating a C3AQX xanthan lyase construct. The treatedplasmid and insert were transformed into One Shot® TOP10F′ ChemicallyCompetent E. coli cells (Invitrogen, Carlsbad, Calif., USA) according tothe manufacturer's protocol and plated onto LB plates supplemented with0.1 mg of ampicillin per ml. After incubating at 37° C. overnight,colonies were seen growing under selection on the LB ampicillin plates.Two colonies transformed with the C3AQX xanthan lyase construct werecultivated in LB medium supplemented with 0.1 mg of ampicillin per mland plasmid was isolated with a QIAprep Spin Miniprep Kit (QIAGEN Inc.,Valencia, Calif., USA) according to the manufacturer's protocol.

Isolated plasmids were sequenced with vector primers and C3AQX genespecific primers in order to determine a representative plasmidexpression clone that was free of PCR errors.

Example 14 Expression of the Paenibacillus sp-18054 Xanthan Lyase inAspergillus

The expression plasmid pC3AQX was transformed into Aspergillus oryzaeMT3568. Aspergillus oryzae MT3568 is an AMDS (acetamidase) disruptedderivative of JaL355 (WO 2002/40694) in which pyrG auxotrophy wasrestored in the process of knocking out the A. oryzae acetamidase (AMDS)gene. MT3568 protoplasts are prepared according to the method ofEuropean Patent, EP0238023, pages 14-15, which are incorporated hereinby reference.

Transformants were purified on COVE sucrose selection plates throughsingle conidia prior to sporulating them on PDA plates. Production ofthe Paenibacillus sp-18054 xanthan lyase polypeptide by thetransformants was analyzed from culture supernatants of 0.75 ml 96 deepwell stationary cultivations at 30° C. in YP+2% glucose medium.Expression was verified on an E-Page 8% SDS-PAGE 48 well gel(Invitrogen, Carlsbad, Calif., USA) by Coomassie staining. Onetransformant was selected for further work and designated Aspergillusoryzae XL-4.

For larger scale production, Aspergillus oryzae XL-4 spores were spreadonto a PDA plate and incubated for five days at 37° C. The confluentspore plate was washed twice with 5 ml of 0.01% TWEEN® 20 to maximizethe number of spores collected. The spore suspension was then used toinoculate seven 500 ml flasks containing 100 ml of Dap-4C medium. Theculture was incubated at 30° C. with constant shaking at 100 rpm. At dayfive post-inoculation, the culture broth was collected by filtrationthrough a bottle top MF75 Supor MachV 0.2 μm PES filter (Thermo FisherScientific, Roskilde, Denmark). Fresh culture broth from thistransformant produced a band of Xanthan lyase protein of approximately90 kDa.

Strains

Aspergillus oryzae MT3568 strain was used for expression of theAcremonium alcalophilum gene encoding the polypeptide havingendoglucanase activity. A. oryzae MT3568 is an amdS (acetamidase)disrupted gene derivative of Aspergillus oryzae JaL355 (WO 2002/40694)in which pyrG auxotrophy was restored by disrupting the A. oryzaeacetamidase (amdS) gene.

Example 15 Activity Screening of Non-Tagged Xanthan Lyase (SEQ ID NO: 4)Expressed in Aspergillus oryzae

Filtered supernatant from a fermentation performed as described inexample 14 was concentrated tenfold by a Vivaspin® 20 centrifugal column(Sartorius Stedim biotech, product number VS2092). Xanthan lyaseactivity in the concentrated sample was measured by viscosity reductionand reducing ends, as described in example 6 for the purified His-taggedenzymes.

Reducing Ends

The method used to determine the amount of reducing ends produced wasthe 2,2′ bicinchoninic acid assay (BCA) as described in Murphy et al.,2012, J. Biol. Chem. 287: 1252-1260 and adapted from Zhang et al, 2005,Biomacromolecules 6: 1510-1515 and Dubois et al, 1956, Anal. Chem. 28:350-356. Quantification of reducing ends was based on a glucose standardcurve. Appropriate substrate and enzyme controls were included andcorrected for in each analysis. Appropriate dilutions were used toensure samples were within the glucose calibration curve range. Theresults are shown in table 17 below

Viscosity Reduction

The viscosity measurements were performed using the Novozymes-developedviscosity pressure assay described in WO2011/107472. 400 μL was thesample size. Results presented are the average of two measurements andare shown in table 16 below.

Hydrolysis

The hydrolysis conditions were as follows: 30° C., 0.25% xanthan gum(XG) in TY medium. Enzyme was added upon thermal equilibration.

Enzyme Doses

The purified enzyme preparations of example 5 were used for the analysisin the following final concentrations:

GH9 (SEQ ID NO: 6): 31.25 mg/L

Xanthan lyase (SEQ ID NO: 4): 31.25 mg/L

The concentration of xanthan lyase in the concentrated supernatant wasestimated to be roughly similar to the purified enzyme based on SDS-pageanalysis.

These results show that adding the GH9 endoglucanase (all five variants)to the wash gives a significant cleaning benefit under the conditionstested. Furthermore, adding the GH9 endoglucanase (all five variants)together with XL results in an additional wash effect even though thexanthan lyase on its own has no apparent effect.

Example 23 Cloning and Expression of 2 GH9 Enzymes from Paenibacillussp-18054 and Paenibacillus sp-62408 in Bacillus subtilis

A linear integration vector-system was used for the expression cloningof the GH9 from Paenibacillus sp-18054 (SEQ ID NO: 85) and the GH9 fromPaenibacillus sp-62408 (SEQ ID NO: 89). The linear integration constructwas a PCR fusion product made by fusion of the gene between two Bacillussubtilis homologous chromosomal regions along with a strong promoter anda chloramphenicol resistance marker. The fusion was made by SOE PCR(Horton, R. M., Hunt, H. D., Ho, S. N., Pullen, J. K. and Pease, L. R.(1989), “Engineering hybrid genes without the use of restrictionenzymes, gene splicing by overlap extension”, Gene 77: 61-68). The SOEPCR method is also described in patent application WO 2003095658. Thegene was expressed under the control of a triple promoter system (asdescribed in WO 99/43835), consisting of the promoters from Bacilluslicheniformis alpha-amylase gene (amyL), Bacillus amyloliquefaciensalpha-amylase gene (amyQ), and the Bacillus thuringiensis cryIIIApromoter including stabilizing sequence. The gene coding forchloramphenicol acetyl-transferase was used as marker (described in e.g.Diderichsen, B.; Poulsen, G. B.; Joergensen, S. T., (1993), “A usefulcloning vector for Bacillus subtilis”, Plasmid, 30:312). The final geneconstructs were integrated on the Bacillus chromosome by homologousrecombination into the pectate lyase locus. The gene encoding the GH9from Paenibacillus sp-18054 was expressed as a truncated version (SEQ IDNO 87). The GH9 from Paenibacillus sp-62408 was expressed as a fulllength gene (SEQ ID NO 91). The gene fragments were amplified fromchromosomal DNA of the corresponding strains with gene specific primerscontaining overhang to the two flanking vector fragments (primersequences are listed in table 30). Both genes were expressed with aBacillus clausii secretion signal (with the following amino acidsequence: MKKPLGKIVASTALLISVAFSSSIASA) replacing the native secretionsignal and both genes were expressed with a poly histidine-tag (HHHHHH)linked to the C-terminal of the protein. A plasmid map of the linearvector with gene insert is shown in FIG. 1.

The 2 vector fragments and the gene fragment were subjected to aSplicing by Overlap Extension (SOE) PCR reaction to assemble the 3fragments into one linear vector construct. This was done independentlyfor each of the two genes. An aliquot of each of the two PCR productswas transformed into Bacillus subtilis. Transformants were selected onLB plates supplemented with 6 μg of chloramphenicol per ml. For eachconstruct a recombinant Bacillus subtilis clone containing theintegrated expression construct was grown in liquid culture. The enzymecontaining supernatants were harvested and the enzymes purified asdescribed in Example 5.

The results presented above show that all of the combinations of thedifferent GH9's and xanthan lyases tested can degrade the xanthanpresent in the media, thus leading to viscosity reduction.

Example 25 Colourmetric Assay of GH9 Endoglucanases on PretreatedXanthan Gum

GH9 endoglucanase activity was determined by reducing ends on xanthangum pre-treated with xanthan lyase using the colorimetric assaydeveloped by Lever (1972), Anal. Biochem. 47: 273-279, 1972. Anyreducing ends that are produced will react with PAHBAH generating anincrease of colour which is proportional to the enzyme activity underthe conditions used in the assay. Table 38 below shows the activity ofGH9 measured by the respective absorbance compared to that of thesubstrate alone.

Materials and Chemicals

0.1% Substrate: 6 ml (5 mg/ml) xanthan gum pre-treated with xanthanlyase in 24 ml Milli-Q water.

Activity buffer: 100 mM sodium acetate, 100 mM MES, 1 mM CaCl2, in 0.01%Triton X100, pH 7.

Ka—Na-tartrate/NaOH buffer: Dissolve Ka—Na-tartrate (50 g) and NaOH (20g) in water to a total volume of 1 liter. Store at 4° C.

Stop solution: Dissolve PAHBAH (Sigma H-9882) in Ka—Na-tartrate/NaOHsolution to a concentration of 15 mg/ml (e.g. dissolve 500 mg PAHBAH in33 ml Ka—Na-tartrate/NaOH solution)

Sample Preparation:

The enzyme samples were diluted to 0.1 mg/ml in activity buffer incostarstrips using a BioMek liquid handler robot. 50 μl of substrate and50 μl of each diluted sample was transferred to a 96-well PCR-MTP plate,50 μl activity buffer was added to each sample and the solutions mixed.The sealed PCR-plate was incubated in a PCR machine at 37° C. for 15min. then immediately cooled to 10° C. 75 μl of the stop solution wasadded to each sample, the mixture was shaken, and 75 μl of each samplewas discarded. The samples were incubated for 10 min. at 95° C., then 1min. 10° C. 150 μl of each sample was transferred to a new 96-wellPCR-MTP and the absorbance at 405 nm was measured.

The data shows that the reaction of xanthan gum pre-treated with xanthanlyase with a GH9 endoglucanase results in a stronger colourmetricresponse. Since the colourmetric response is proportional to the amountof reducing ends produced, then it can clearly be seen that the GH9endoglucanases have activity on xanthan gum pre-treated with xanthanlyase.

Example 26 Colourmetric Assay of Xanthan Lyases on Xanthan Gum

Xanthan lyase activity was determined by reducing ends as described inexample 25, except that 0.1% xanthan gum was used as substrate. Theresults are presented in table 39 below.

The data shows that the reaction of xanthan gum with a xanthan lyaseresults in a stronger colourmetric response and therefore the xanthanlyases have activity on xanthan gum.

Responses are set relative to the response of xanthan lyase of SEQ IDNO: 8 which is set to 100.

The data shows that the reaction of xanthan gum with a xanthan lyaseresults in a significantly stronger colourmetric response and thereforethe xanthan lyases alone have significant activity on xanthan gum.Furthermore, addition of the GH9 endoglucanase of SEQ ID NO: 6 resultsin at least a 3-4 fold increase in colourmetric response over the use ofthe xanthan lyase alone, showing that use of the two enzymes togetherresults in a synergistic degradation of xanthan gum.

Example 28 MiniLOM Wash Performance of Xanthan Lyase (SEQ ID NO:) and/orGH9 (SEQ ID NO:)

The enzymes of the present invention were tested using the miniLOM assayin order to determine the “enzyme detergency effect”. Test tubes arefilled with test solution, soiled fabrics and steel balls and rotated ina heating cabinet at a given temperature. Cleaning benefits are studiedwhen washing in model liquid detergent A. The experimental conditionsfor the experiments are specified in Table 41.

Water hardness was adjusted by addition of CaCl₂, MgCl₂, and NaHCO₃ tothe test system. After washing the textiles were flushed in tap waterand air-dried. The swatches were prepared by adding xanthan gum fromXanthomonas campestris (Food Grade Keltrol T, Kelco) mixed with carbonblack to a cotton fabric. The DN31C swatch is prepared with half theamount of xanthan gum; otherwise it is identical to the DN31 D swatch.However, this does have the effect of reducing the measurement windowfor enzymatic effects, in that the amount of xanthan gum which may beremoved is reduced. In effect, this leads to a smaller increase inintensity when compared to the detergent alone effects, but should notbe construed as a lesser enzymatic effect.

The performance of the enzyme(s) is evaluated by measuring the remissionof the textile swatches using the ColorEye at 460 nm. The results usingswatch C are presented in tables 42 and 43, whilst the results usingswatch D are presented in tables 44 and 45.

Example 29 Xanthan Degrading Activity of GH9 Endoglucanases and XanthanLyases by Measurement of Viscosity Reduction

Viscosity measurements were carried as described in example 10 on twodifferent batches of the GH9 endoglucanase of SEQ ID NO: 6 and a singlebatch of the GH9 endoglucanase of SEQ ID NO: 2 together with twodifferent xanthan lyases (SEQ ID NO: 8 and 66). SEQ ID NO: 6 isidentical to SEQ ID NO: 2 except that it contains a His-tag (i.e.—RPHHHHHH) attached to the N-terminal of the mature polypeptide. Theconcentration of the purified enzyme preparations used for the analysiswas 31.25 mg/L. Results presented are the average of three measurementsand are shown in table 46 below.

The results in table 46 show that there is no significant difference inthe drop in viscosity between the two batches of the GH9 endoglucanaseof SEQ ID NO: 6 which has a His-tag and the GH9 endoglucanase of SEQ IDNO: 2 which is without the His-tag together with either xanthan lyase.It can therefore be concluded that the His-tag does not alter thexanthan gum degrading properties of the GH9 endoglucanase of SEQ ID NO:2.

Example 30 Colourmetric Assay of GH9 Endoglucanases and Xanthan Lyaseson Xanthan Gum

The activity of GH9 endoglucanases alone and in combination withdifferent xanthan lyases on xanthan gum was determined by reducing endsas described in example 25, except that 0.1% xanthan gum was used assubstrate. The results are presented in table 47 below.

The results demonstrate that all of the GH9 endoglucanases together withall of the xanthan lyases tested give a significant increase incolourmetric response showing that the combination of these GH9endoglucanses and xanthan lyases has significant activity on degradingxanthan gum. The results further show that there is no significantdifference between the two batches of the GH9 endoglucanase of SEQ IDNO: 6 tested, nor that the His-tag which is present on the GH9endoglucanase of SEQ ID NO: 6 results in any significant change inperformance over the corresponding GH9 endoglucanase without His-tag(SEQ ID NO: 2).

Example 31 AMSA Wash Performance of Xanthan Lyases and GH9Endoglucanases

The experiments were conducted as described in the Automatic MechanicalStress Assay (AMSA) for laundry method using a single cycle washprocedure and the experimental conditions specified in table 48 below.The results are given in tables 49 and 50 using 3 different GH9endoglucanases and 6 different xanthan lyases along along with controlswhere either the GH9 endoglucanase and/or xanthan lyase are absent. Theresults are shown as the ΔInt enzyme value.

The swatches were prepared by adding xanthan gum fromXanthomonas campestris (Food Grade Keltrol T, Kelco) mixed with carbonblack to a cotton fabric. The DN31C swatch is prepared with half theamount of xanthan gum; otherwise it is identical to the DN31 D swatch.However, this does have the effect of reducing the measurement windowfor enzymatic effects, in that the amount of xanthan gum which may beremoved is reduced. In effect, this leads to a smaller increase inintensity when compared to the detergent alone effects, but should notbe construed as a lesser enzymatic effect.

TheGH9 endoglucanase of SEQ ID NO: 100 shows a significant wash effect withthe xanthan lyase of SEQ ID NO: 66 at both 20° C. and 40° C.

Example 32 MiniLOM Wash Performance of GH9 Endoglucanase

The GH9 endoglucanases were tested using the miniLOM assay in order todetermine the enzyme detergency benefit of the GH9 endoglucanase. Theenzyme detergency benefit was studied by comparing the wash effect onxanthan gum with carbon black stains with and without a GH9endoglucanase in either buffer (2-(N-morpholino)ethanesulfonic acid,MES), or model detergent A using the conditions described in table 51.The results for stain DN31C are given in tables 52 and 53 and for stainDN31 D are given in tables 54 and 55.

Water hardness was adjusted by addition of CaCl₂, MgCl₂, and NaHCO₃ tothe test system. After washing, the textiles were flushed in tap waterand air-dried. The swatches were prepared by applying a mixture ofcarbon black (0.05-0.06 g) and xanthan gum (1.2-1.4 g for DN31C, 2.4-2.6g for DN31 D, Xanthomonas campestris (Food Grade Keltrol T, Kelco) persquare meter of cotton fabric. The enzyme detergency benefit of theenzyme(s) was evaluated by measuring the remission of the textileswatches using the ColorEye at 460 nm as described in the Evaluation ofStains.

The results showed that there was significant enzyme detergency, stainremoval and cleaning benefits when the GH9 endoglucanase (SEQ ID NO: 6)was added to the wash solution using either buffer (50 mM MES) or withmodel detergent A. Tables 52 and 54 show that the same enzyme detergencybenefit was observed when between 0.2 and 0.8 mg enzyme protein per Lwash liquor was used, indicating that a plateau level may already havebe reached when dosing above 0.2 mg EP/L.

Repeating the experiment using lower amounts of endoglucanase (SEQ IDNO: 6) (tables 53 and 55) showed that significant enzyme detergencybenefit was apparent even at 0.05 mg enzyme protein per L wash liquor.The addition of 0.5 ppm bovine serum albumine instead of the GH9endoglucanase showed that the enzyme detergency benefit was not due toan unspecific protein effect.

The largest effect can be seen on stain DN31D where benefits of up to 7delta REM units were found when using either buffer (50 mM MES) or withmodel detergent A.

Example 33

Effects of GH9 Endoglucanase on (Pre-Treated) Xanthan Gum as Determinedby Viscosity Reduction

0.5% pre-treated xanthan gum was prepared by pre-treating the xanthangum with xanthan lyase as described in Nankai, H., Hashimoto, W., Miki,H., Kawai, S., and Murata, K. (1999) “Microbial system forpolysaccharide depolymerization: Enzymatic route for xanthandepolymerization by bacillus sp strain gl1”, Applied and EnvironmentalMicrobiology 65, 2520-2526. Prior to use all enzymes were buffer changedto the MES buffer using NAP 5 columns (GE Healthcare).

The samples were hydrolysed using the following conditions: 0.25%xanthan gum or 0.5% pre-treated xanthan gum in 50 mM MES buffer+0.01%triton x-100 at pH 7.0 and 40° C.

The initial viscosity was measured upon thermal equilibration and priorto enzyme addition using the ViPr assay. After thermal equilibration,the GH9 endoglucanse (SEQ ID NO: 6) (20 mg/L), if appropriate, was addedand the viscosity was then measured at various time points. The data ispresented in table 56 below.

The buffer control represents the viscosity representative of completehydrolysis. At this point there are little to no solvent-polymerinteractions which would lead to an increase in solvent viscosity. Thexanthan gum and modified xanthan gum controls remain constant throughoutthe incubation displaying the robustness of the assay. The GH9endoglucanase (SEQ ID NO: 6) is seen to decrease the xanthan gumsubstrate over the course of the 3 h incubation but the viscosity doesnot reach the viscosity of the control. The xanthan lyase pretreatedxanthan gum is reduced to the buffer viscosity almost immediately underthese conditions by the GH9 endoglucanase (SEQ ID NO: 6).

Example 34 Effects of GH9 Endoglucanase on (Pre-Treated) Xanthan Gum asDetermined by Reducing Ends

0.25% pre-treated xanthan gum was prepared by pre-treating the xanthangum with xanthan lyase as described in example 33. Prior to use allenzymes were buffer changed to the MES buffer using NAP 5 columns (GEHealthcare). The samples were hydrolysed using the following conditions:0.25% xanthan gum or 0.25% pre-treated xanthan gum in 50 mM MESbuffer+0.01% triton x-100 at pH 7.0 and 30° C.

After thermal equilibration, the GH9 endoglucanse (SEQ ID NO: 6) (62mg/L), if appropriate, was added and the produced reducing ends weremeasured at the end point using the BCA Reducing Ends assay.Quantification of reducing ends was based on a glucose standard curveand the results are shown in table 57 below.
